Contribution

It introduces NFL corrections to the calculation of pulsar kick velocities and specific heat in magnetized quark matter, enhancing the understanding of neutron star dynamics.

Findings

NFL corrections significantly alter kick velocity estimates

Relation between radius, temperature, and kick velocity demonstrated

Results show deviations from normal Fermi liquid predictions

Abstract

In this work we calculate pulsar kick velocity of magnetized neutron star composed of degenerate quark matter core with non-Fermi liquid (NFL) correction. Both the leading order (LO) and next to leading order (NLO) corrections to the kick velocity have been incorporated. In addition, the NFL corrections to the specific heat of magnetized quark matter have been presented. This has been taken into account to calculate the kick velocity of the neutron star. Results show significant departure from the normal Fermi liquid estimates. The relation between radius and temperature has been shown with kick velocity of $100\, km/s$ with and without NFL corrections.
